I know mucus with stool is common symptom of IBS and I have that once in a while. I know mucus is a nonspecific response. Sometimes I feel like I got to pass gas and mucus comes out and when I go to the bathroom to avoid this I get explosive gas and mucus come first and stool later. I saw my doctor last year and he did a colonoscopy last year and said everything was fine but he didnt take a biopsy. I was under stress last year and when the stress was over I only had 2 episodes. My question is this IBS or should I see my gastro again because he didnt take biopsy during the colonoscopy even though he said everything looked normal during my colonoscopy?
